DUBAI, Feb 19 (Reuters) - Stock markets in the Gulf were mixed in early, quiet trade on Sunday with Saudi Arabia and Qatar outperforming because of support from the banking sector as United Arab Emirates bourses succumbed to profit-taking.

Nine of the 12 listed banks on Saudi Arabia's bourse .TASI gained in the first 45 minutes of trade, lifting the index 0.4 percent.

The largest Islamic lender, Al Rajhi Bank 1120.SE , added 1.5 percent after its chief executive told Reuters that the bank gained market share in corporate banking last year for the first time in four years, and would continue to expand in that area by focusing on healthcare services, affordable housing, transportation and energy. urn:newsml:reuters.com:*:nL8N1G048O

Most petrochemical shares were also bid higher, with National Industrialization 2060.SE (Tasnee) up 1.2 percent.

Southern Cement 3050.SE rose 0.4 percent after saying it would pay a cash dividend of 2.25 riyals per share for the second half of 2016, taking the full-year dividend to 4.75 riyals. That, however, is lower than the 6 riyals per share paid out for 2015.

In Qatar, the index .QSI rose 0.6 percent. The largest listed stock, Qatar National Bank QNBK.QA , was up 1.4 percent.

Dubai's index .DFMGI , however, pulled back 0.5 percent, dragged lower by a 2.9 percent fall by builder Arabtec ARTC.DU and a 1.8 decline in Drake & Scull DSI.DU

Shuaa Capital SHUA.DU climbed 3.1 percent on optimism over the investment company's new strategy, which was announced this month and includes an acquisition. urn:newsml:reuters.com:*:nD5N1FJ004

Large caps weighed on Abu Dhabi's index .ADI , which fell 0.3 percent. First Gulf Bank FGB.AD lost 1.1 percent and Etisalat ETEL.AD was down 0.5 percent.
